The purpose of this study was to investigate the causal relationship among perceived value, satisfaction and revisit intention for visitors of the Korea National Arboretum. Three hundred respondents were selected by quota sampling, and well-known measurement scales utilized in marketing field were adopted in order to measure three variables with some modification to apply for arboretum visitors. Results of structural equation model showed that perceived value affected visitors' satisfaction, which in turn influenced revisit intention. Specifically, "emotional value" had the most significant influence on satisfaction, followed by "value for money" and "novelty value"; however, "social value" was not an influential construct. Based on calibration results, several strategies were suggested for the effective management. Authors advised that (a)improvement of measurement scale of value, (b)inclusion of self-congruity as antecedent variable to satisfaction, (c)changing revisit intention to word-of-mouth communication as a post-purchase behavioral intention, and (d)implementation of market segmentation should be considered for future research.

The empirical law that transverse dunes migrate inversely with their heights leads logically to the prediction that multiple dune ridges will converse to a single huge dune by merging. This contradicts the existence of the steady state dune fields on the Earth. The recent studies have emphasized dune collisions as a key mechanism to the stability of dunefield. The roles of wind shadow aspect ratio, however, have yet to be fully explored. This research aims to investigate the potential roles of wind shadow aspect ratio in the dynamical behaviors of transverse dune field. The simplified model is established for this, based upon allometric properties of transverse dunes, wind speedup on the stoss slope and sand trapping efficiency. The derived governing equations can be transformed to the zoning criteria and vector field for dune evolution. The dynamics analysis indicates that wind shadow aspect ratios do not produce convergent areas on the behavior space; rather, they just act as one of the factors that affect the trajectories of dune evolution. Though the model cannot represent the stability of dune field, but seem to produce a reasonable exponent for dune spacing-height relations.

본 연구에서는 정신분열증 환자들이 정서상태를 개념화하고 얼굴표정을 통하여 타인의 정서 상태를 판단하는 과정을 정상인과 비교하였다. 연구1에서는 만 19세-46세의 정신분열병 환자 19명에게 정서 관련 형용사 15개로 구성된 105개의 형용사 쌍에 대하여 유사성을 평정하도록 하여 MDS로 분석한 결과, 쾌/불쾌와 각성의 두 차원이 일관되게 보고되고 있는 정상집단과는 달리 정신분열병 집단의 자료에서는 쾌/불쾌 차원만이 뚜렷하게 나타나고 각성 차원은 얻어지지 않았다. 연구 2에서는 다양한 정서를 표현한 얼굴 사진 28개를 정신분열병 환자 30명과 대학생 31명에게 제시하고 각 사진의 인물이 경험하고 있는 내적 상태를 쾌/불쾌와 각성의 두 차원에 대하여 각각 7점 척도로 평정하도록 한 결과 정신분열병 집단은 대학생 집단에 비하여 쾌/불쾌 차원에서는 보다 긍정적으로 평정하는 경향이, 각성 차원에서는 상대적으로 낮게 평가하는 경향을 나타냈다. 특히 부정적이고 각성 수준이 높은 내적 상태를 표현하는 사진 자극에 대하여 정신분열병 환자 집단이 각성수준을 과소평가하는 경향이 두드러지게 나타났다. 이와 같은 결과를 종합하여 볼 때, 정신분열병 환자들은 정서상태의 개념화 과정에서 각성 차원에 대하여 상대적으로 낮은 민감도를 보이고 있으며, 특히 부정적인 정서상태를 표현하는 얼굴들에 대란 판단에서는 각성 차원을 과소평가하여 높은 각성수준을 나타내는 표정과 낮은 각성수준을 변별하는데 어려움을 보이는 것으로 해석될 수 있다. 본 연구의 결과는 정신분열병 환자들은 자율신경계의 높은 각성 수준으로 인하여 각성 수준을 더 높일 가능성이 있는 자극을 회피하는 경향이 있다는 Mednick의 가설과 일관되는 결과로 이들의 각성 수준에 대한 낮은 민감도는 방어적인 회피성향의 지속에 따른 둔감화의 결과로 해석될 수 있다. 효과는 GSR를 비롯한 자율신경계지표에서 잘 반영되었다.^2$=.792가 되었다. 설명되는 누적분산값은 67.18%였다.주관적 평가의 결과와 객관적 평가 결과를 이용해 마직물의 태를 평가하는 산출식을 제시하였다. 태 평가치의 경우 16가지 특성치를 모두 넣는 방법과 stepwise 방법, 또 Kawabatark 사용한 순차적 군 회귀법의 세가지 방법의 회귀식 중 16가지 특성치를 모두 넣는 방법의 결정계수가 가장 높았다.tosterone농도는 107.7$\pm$12.0 pmol／l이었고, 남성의 타액내 농도는 274.2$\pm$22.1 pmol／l이었다. 이상의 결과로 보아 본 연구에서 정립된 EIA 방법은 RIA를 대신하여 소규모의 실험실에서도 활용할 수 있을 것으로 사려된다.또한 상실기 이후 배아에서 합성되며, 발생시기에 따라 그 영향이 다르고 팽창과 부화에 관여하는 것으로 사료된다. 더욱이, 조선의 ${\ulcorner}$구성교육${\lrcorner}$이 조선총독부의 관리하에서 실행되었다는 것을, 당시의 사범학교를 중심으로 한 교육조직을 기술한 문헌에 의해 규명시켰다.nd of letter design which represents -natural objects and was popular at the time of Yukjo Dynasty, and there are some documents of that period left both in Japan and Korea.

The purpose of this study is to develop a science field study area using Geumgang(Geum River), fossil origins and various geological resources in Youngdong area of Chungcheongbuk-do as educational resources; and utilize them to develop an education program to cultivate earth science and topophilia. The Youngdong sedimentary basin (Cretaceous period) has a well-developed outcrop along the Geumgang and it is therefore easy to find various geological structures, plant fossils, and dinosaur fossils. Also, it has a distinct sedimentary structure, such as mud cracks, ripple marks and cross-bedding. Science field study area(6 observation sites) were developed based on school curriculum, textbook analysis, and professional earth science education panel discussion to create a convergence education program. The result of validating the developed program showed that all the items were satisfactory ($CVR{\geq}0.88$) in the test categories. The science field study teaching-learning model was applied to actual classes. The evaluation result for class satisfaction was positive, scoring Rickert scale 4.18. The result of observation about the outdoor classroom process in the science field study area revealed that students were able to form a new image of the beautiful scenery of the Geumgang. Also, the students could gain a new understanding, concept and value of various geological objects (sandy beach, stepping-stones, dinosaur footprint fossils, sedimentary formation), which naturally allowed them to form topophilia.

It is said that customers buy not products but brands embedded in their mind, so that they are used as a key tool of strong marketing strategy. The present paper is a study on service brand equity, on which much research has not been conducted. The purpose of the present study is to propose the way to manage service brand equity which is essential to gaining competitive superiority by examining the effect of the factors of marketing communication on it. The researcher presented a research model by inquiring into existing researches on marketing communication and service brand equity and set up a research hypothesis. Internet service was chosen as the subject of the study. The reason for this is that it is the most intangible and there is no difference in price and quality, so that it is actively being marketed. The present positive study verified the relation between the factors of marketing communication such as advertising, public relations, sales promotion, and word-of-mouth advertising and brand recognition, brand image, and brand loyalty. The results of the positive study are as follows. Advertising, sales promotion and word-of-mouth advertising had an effect on brand recognition. Public relations, sales promotion and word-of-mouth advertising had an effect on brand image. Brand image and brand recognition affected brand loyalty.

There are 11,811 LWR spent fuels stored at reactor sites, as of 2009. Source terms based on reference spent fuel which represents entire spent fuels with bounding values in the aspect of source term has been applied to a design of nuclear installations, instead of those which are generated by weighting respective source term for each spent fuel. Simplified regression models to estimate total decay heat, radioactivity, and ingestion hazard index for spent fuel from Westinghouse-type reactors were developed in this study, because it can be used as a fundamental model for weighting source term for respective spent fuel to exclude conservativeness in source terms. It was found that the estimated source terms agreed with calculated value from ORIGEN-ARP within 5%. It was also found that the conservativeness could be excluded if the weight source terms were used as reference source term in the design. Therefore, it is expected that the developed regression model could be widely used in the conceptual design process of nuclear facilities related with storage and disposal of spent nuclear fuel.

This study aimed to identify influencing factors such as job environment, job characteristics, and job competency as they are related to newcomer turnover intentions in the construction of landscape architecture, Korea. The results based on statistical analyses are follows as: The turnover experience of newcomers in the field of landscape architecture construction was 54.5%, about 1.6 times higher than in other fields. The influencing factors among newcomer turnover intentions in the construction of landscape architecture were workload(p<0.01), job suitability, and personal relations(p<0.01), while in job autonomy, work conditions, job competency, job identity, job variety, and job compensation were not statistically significant. This study found that key important factors of dependent variables that conceptually explain the influence of turnover intentions among newcomers differed between the construction of landscape architecture and other fields. The most important factors in turnover intention were workload>personal relationship>job suitability among independent factors. This study implied that efforts for improvement are needed in areas of workload, personal relations, and job suitability to mitigate newcomer turnover intentions so as to establish common and personal goals in the field of landscape architecture construction because turnover intention could lead losses in human resources, time, economy, and psychological health. In conclusion, this study suggested the importance of efforts for human resource management to reduce turnover intentions among newcomers in the field of landscape architecture construction.

Recently, enterprises are protecting information assets with the various means of control and management. Nevertheless, they are confronted with the dilemma which the higher securitylevel they request, the lesser efficiency and productivity in short terms they acquire by the inconvenience of business process. In addition, in spite of the steady increase of organization's investment on information protection, the systematic way for the performance measurement of information protection has not been suggested, so that in reality, it is difficult to make the decision to invest on information-protection and elicit the direction to improve it. For this reason, this study intended to establish the concept of the protection and security of information assets of enterprises and to categorize the type of activities to protect information assets into management activity and control activity, and analyze the effects of management activity and control activity for information asset protection on the performance of information asset protection activity and organization. For this research, questionnaire survey was conducted with literature study and the PLS(Partial Least Square) was used to analyze the measurement model and hypotheses testing. The PLS analysis results indicate that management activity for information asset protection affects information asset protection performance. Further, organizational performance is influenced by information asset protection performance. Practical implications of these findings and future research implications are also discussed.

Given the importance of ensuring continued residency and maintenance of the 1st Planned New Town, which is the first of more than 20 such projects, this study aims to identify the factors determining the residents' living intention. The results show that age, gender, length of stay, and occupancy type are significant factors influencing their living intention. Among the environmental factors, the educational environment and shopping environment are crucial. This means that in order to achieve the "Ageing in Place" concept, it is necessary to improve the educational environment, provide a variety of commercial facilities and expand the living facilities. While it has no direct influence on the pros and cons of building remodeling, the results showed that when the living intention is used as a parameter, the transportation, educational, and shopping environment have an indirect influence on the pros and cons of building remodeling.

A particle tracking scheme was developed in order to model radionuclide transport through a tortuous flow Held in a rock fracture. The particle tacking method may be used effectively in a heterogeneous flow field such as rock fracture. The parallel plate representation of the single fracture fails to recognize the spatial heterogeneity in the fracture aperture and thus seems inadequate in describing fluid movement through a real fracture. The heterogeneous flow field une modeled by a variable aperture channel model after characterizing aperture distribution by a hydraulic test. To support the validation of radionuclide transport models, a radionuclide migration experiment was performed in a natural fracture of granite. $^3$$H_2O$ and $^{131}$ I are used as tracers. Simulated results were in agreement with experimental result and therefore support the validity of the transport model. Residence time distributions display multipeak curves caused by the fast arrival of solutes traveling along preferential fracture channels and by the much slower arrival of solutes following tortous routes through the fracture. Results from the modelling of the transport of nonsorbing tracer through the fracture show that diffusion into the interconnected pore space in the rock mass has a significant effect on retardation.
